Third-party reviews

Based on ratings from across the web.
Reviews last updated: November 2026 · How we calculate this

What customers like about Ultrasone HFI 680

  • Impressive bass response with good punch and attack
  • Wide soundstage for a closed-back headphone due to S-Logic technology
  • Extremely durable construction and 'rock solid' design
  • Relatively balanced sound profile compared to other HFI models
  • Effective passive noise isolation and minimal sound leakage
  • Foldable design makes them convenient for storage and travel

What customers don't like about Ultrasone HFI 680

  • Stock cable is noted as being too long (3m), thick, and stiff for portable use
  • Strong clamping force can be uncomfortable and may require manual stretching of the headband
  • Slight lack of detail in the upper treble and occasional harshness
  • Mids can lack texture and detail compared to high-end open-back alternatives
  • Requires a significant amount of burn-in time (up to 500 hours according to some users)
  • Pleather ear pads can cause heat build-up during long listening sessions

Verdict

The Ultrasone HFI-680 is a closed-back dynamic headphone featuring 40mm gold-plated drivers, a frequency range of 15 Hz to 25,000 Hz, 75 Ohm impedance, and 99 dB sensitivity. Utilizing proprietary S-Logic Plus technology for a more natural surround soundstage and ULE (Ultra Low Emission) MU-metal shielding to reduce electromagnetic radiation by up to 98%, it offers a balanced sound signature with punchy bass and detailed highs. Main advantages include its foldable, durable design, excellent passive noise isolation, and high efficiency that allows it to be driven easily by portable devices. However, potential drawbacks include a long, non-detachable 3-metre cable that can be microphonic and stiff for mobile use, a high initial clamping force that may require stretching for comfort, and a tendency for the treble to be slightly sharp or sibilant before a significant burn-in period.
